EMBEDDED IHJEL-PROTECTING- PLATE.

S ecification of Letters Patent.

Patented May 11, 1909.

Application filed October 8, 1908. Serial No. 456,724.

of Mount Brydges, Ontario, Canada, residing at the present at Eflingham, Illinois, have invented certain new and useful Improvements in Embedded Heel-Protecting Plates,

of which the following is a specification.

My invention relates to improvements in embedded shoe or boot heel-protecting plates, and the object thereof is to produce a heelprotecting plate which will require the removal of only about one'half ofthe usual slice in the ply of leather in which it is to' be embedded, and which is constructed so as to prevent stubbing and so as to interlock with the heel in a manner as to resist retroaction. l attain these objects by the construction illustrated in the accompanying drawing, in which i Fi re 1 is a view of the bottom of a heel provided with my plate; Fig. 2, a section taken on the line X-X of Fig. 1the plate being in this view in the wearing position; and Fig. 3, an enlarged view in perspective of the late proper.

Simi ar letters of reference denote corresponding parts throughout the several views.

My heel-protecting plate is formed segmental in its contour, that its outer end, or periphery, may conform to the periphery, or convexity, of the heel, and right-angulartriangle like in its cross section, thatit present a large surface to wear and be amply broad and thick only at the point where it is subject to greater attrition. In consequence of these features of construction the plate wearslonger, is lighter in weight, and

requires less leather to be removed of the lift in the heel in which it is to be embedded.

in constructing the plate, the surface of the base plane a and the periphery b are shaped so as to be at right angles to each other; the surface of the base plane a, the periphery b, and the surface of the top plane 0 thcrcof, so as to form a right-angular trianglewhen'viewed in side elevation or in cross section. The end d, opposite the periphery b, is beveled off from the level plane (1 to the inr clined plane 0 to a blunt knife edge. In the l inclined surface, or top plane, 0 are formed a plurality of transverse serrations e, shaped so as to incline toward the periphery I). About in the middle of the breadth and length of the late thus constructed is a countersunk ho e f all as clearly shown in Figs. .2 and 3.

In fitting my plate to the heel A, a rightangular-triangle like seat B of the proper length and breadth and of a depth corre sponding to the thickness of the plate less the height of the serrations e and edge of the end (1, is cut out in the heel at the point requiring' reinforcement. The plate is then first driven into the seat B laterally, so as to bury the edge of the end (Z in the leather, and then hammered into the seat B until the surface of the base a is level with the surface of the heel; thereby causing the serrations e to im press in the seat B corresponding serrations, but inclined in the opposite direction, and thus interlock with the heel. this means the plate resists the tendency to retrograde under the influence of the friction produced by a shufiiing gait of the wearer. A coneheaded nail C is then driven into the heel through the holef which nail holds the plate securely in position.

than the metal of the protecting plate, the edge and corners of the forward end of the plate heretofore caused stubbing scratching polished lioors or abrading carpets the wearer ofthe plate walked on. Bet cling oil the end (1 to an edge and burying the edge in the leather of the heel will effectually prevent stubbing and scratchin floors or carpets long. after the surface of tlie heel B has begun to wear.

Having described my claim is- 1. A heel-protecting plate formed segmental in its contour with the lane of its uper surface inclined toward tiie plane of its ower surface, its thinner end beveled off from said lower surface toward the plane of said upper surface, and serrations formed in said upper surface inclining toward the i thicker end of the plate.

2. A shoe heel having a right-angular-triinvention, what- I As the leather of the heel wears sooner an 'le like seat with a heelrotectin late In testimon T whereof I allix 111v siq'nature b p g 3 C ofcorresponding formation embedded t erein presence of two Witnesses.

' in having its thinner end beveled ofl from its Slum-FL TOLES level toward its inclined plane and the beveled oil portion embedded in the heel, and inclined serrations in thecontactual surface of said plate and heel.
